Destination array is not long enough

[Darren]

I am getting an error when I try to bind the radgrid promethius. I had this working in the asp.net radgrid version, but decided to upgrade to the most current version of promethius. Thanks

Error: Destination array is not long enough to copy all the items in the collection. Check array index and length.

I just found out that if I remove the grouping it works - so it is the grouping that is causing a problem for some reason. Also, the skin mentioned about should be 'Outlook' and not 'Outlook2007'. Thanks.

Hello Darren,

Do you experience this issue with the latest version Q3 2007 SP1 of RadControls Prometheus? If the issue is still there after applying the hotfix, I suggest you prepare a stripped working version of your project and send it attached to a formal support ticket. I will examine your code implementation in detail and will get back to you with more info.

Best regards,
Stephen

Hi, I was able to get it working. As mentioned it is fixed in sp1. For some reason the automatic installation of this package did not overwrite my version 1218 dll's. I tried a few times and same problem. So, I downloaded the hotfix dll's and all is good.

Thanks.
